Title:
INSULIN INJECTOR CAPABLE OF DOSAGE MEASUREMENT USING PHOTOSENSOR
Document Type and Number:
WIPO Patent Application WO/2018/056606
Kind Code:
A1
Abstract:
The present invention relates to an insulin injector capable of dosage measurement using a photosensor and to an insulin injector which is capable of dosage measurement using a photosensor and comprises: a drug cartridge (10) which stores insulin and in which a movable piston (11) is provided; an injection driving unit (20) comprising a plunger (23) for compressively driving the piston (11); and a main control unit (40) for controlling the driving of the injection driving unit (20), the insulin injector (100) further comprising: a light reflector (110) installed at the other end of the plunger (23); and a dosage measuring unit (120), which comprises an optical transmission unit (121) for transmitting an optical signal towards the light reflector (110), an optical reception unit (122) for receiving the optical signal reflected by the light reflector (110), and a dosage calculation module (123) for comparing the optical signal transmitted by the optical transmission unit (121) with the optical signal received by the optical reception unit (122) and measuring the linear travel distance of the plunger (23), and which transmits, to the main control unit (40), the linear travel distance of the plunger (23) calculated by the dosage calculation module (123).
